Default Radiating Efficiency

Reg Edwards wrote:
Cecil, could you or somebody, please use Eznec or something, to
determine the radiating efficiency of a 9.0 meter long vertical
antenna with a ground-loss connection resistance of 5 ohms, at its
1/4-wave resonant frequency slightly above 8 MHz.


Is the 5 ohms of ground loss the only loss in the system?
i.e. should perfect ground be used? Or should it be done
in free space with a 5 ohm load going to the radials.

Will integrating the area of the omnidirectional elevation
envelope yield a value proportional to the radiated power?
